Comparative Analysis of Aroma Compositions of Two Camellia Chrysantha (Hu) Tuyama Species

Biochemical components in the leave of two Camellia chrysantha(Hu) Tuyama species were analyzed.The results showed that,the contents of water,water extract,total flavonoids and soluble sugar of Camellia nitidissima were 6.18%,30.16%,0.214% and 10.09%,respectively.For Camellia euphlebia the contents of those components were 10.06%,18.97%,0.445% and 3.69%,respectively.The content of total free amino acid in Camellia nitidissima was 6.5643 mg/g.The content of total free amino acid in Camellia euphlebia was 1.2720 mg/g.For the content of tea polyphenols,both of the samples were little.In general,Camellia nitidissima was more than Camellia euphlebia.As for aroma compositions,Camellia nitidissima was identified for 45 kinds,Camellia euphlebia was identified for 26 kinds.Camellia nitidissima was different from Camellia euphlebia in the contents of biochemical components.The development of Camellia nitidissima is more valuable.
